NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Oct. 16, 1906,

Application filed y 16, 1906. Serial No. 317,048.

To (I/ZZ whom, it may concern.-

Be it known that I, GOULD O. HILDE- BRAND, a citizen of the UnitedStates, resid- 1ng at Baltimore, in the State of Maryland, have inventedcertain new and useful Improvements in Non Refillable Bottles, of whichthe following is a specification.

This invention relates to an improved nonrefillable bottle.

The object of the invention is to provide an improved glass passage-wayfor insertion within the neck of an ordinary bottle, where it is to bepermanently secured, and which will permit the liquid contents to bepoured out, but will prevent liquid from being put into the bottle.

The invention is shown in the accompanying drawings, in which Figure 1is a vertical section of the neck of a bottle having the improved devicein position. Fig. 2 is a cross-section of the neck of the bottle on theline 2 2.

It is common to find bottles in ordinary use that have the interiorportion of the neck near the mouth end slightly flaring or expanded, asat a, the smallest part of the neck internally being at the point I),where the innermost end of the stopper 0 will come when the stopper hasbeen forced in. The interior of the neck, extending from the saidsmallest part down to the body of the bottle, gradually expands, as at(1. Thus at one point the interior of the neck has its smallestdiameter, and therefrom upward and downward the, neck is slightlyexpanded.

I take a glass tube and by subjecting it to heat produce the followingform: At the up- .per end is an outward flange e, which fits snugly uponthe lip edge f of the bottlemouth. Below said outward flange the tubehas a gradually-contracted part a, which snugly fills the expanded parta of the bottleneck near its mouth, and the stopper 0 may be enteredtightly in said gradually-contracted part of the tube. At its lower endthe tube is round, as at g, and has a bottom h with a central port i.This shape of the tube at the lower end results in forming a smallcircular chamber 3', which contains the head is of a valve, having atits under side a pendent tapered plug k, which closes the said centralport i, the tapered plug projecting through said port and below thebottom h. The length of the tapered plug is as com.

pared with the height of the chamber j is enough greater to insure thatthe point end of the plug will never withdraw from the port i. Theportion of the glass tube between the upper end a. and the chamber 7' inthe lower end has serpentine bends Z, which prevent the insertion ofavwire.

It will be seen that the above-described glass tube has its top endfitted in direct contact with the upper expanded end a of thebottle-neck and that the portion of the glass tube below. the smallestdiameter b of the neck of the bottle is secured within the neck bysuitable cement m, which fills the space around said tube and betweenthe tube and the interior wall of the neck.

When it is desired to pour out any part of the liquid contents of thebottle, the stopper 0 must of course first be removed. Then upon tiltingthe bottle the valve will uncover the port i and the tapered plug lcwill slide through the port i, the small end of the plug still remainingwithin said port; but the latter will be opened sufiicient to permit theliquid to flow out. As the small end of thetapered plug 7c will nevercompletely withdraw from the port i, the valve will resume 'the closedposition shown in the drawings whenever the bottle is standing upright.I

It will be understood that ordinary bottles now in use have thecontraction b in the neck between its ends, and this fact enables theapplication of my improved device to all of such bottle-necks, as thecement filling may be readily expanded by slightly rotating the glasstube, so as to fill the larger portion of the neck below thecontraction. After the cement once sets it is obviously impossible towithdraw the tube from the neck.

Having thus described my invention, what end fits in direct contact withsaid upward expanded part of the neck-said top end of the tube having aninternal size adapted to receive the stopper, and the tube having aseries of serpentine bends extending down ward and at its lower endprovided with a circular chamber having a port; and a valve having ahead which is confined in said chamber and provided with a plug whichenters said port.

2. The herein-described non-refillable bottle, comprising a glass tubewhose upper end fills the mouth of the bottle, and whose lower end has acircular chamber having a port and provided with serpentine bendsbetween said the plug as compared with the height of the chamber beingenough greater to insure that -in operation the point end of the plugwill never withdraw from said port.

In testimony whereof I aflix my slgnature in presence of two witnesses.
